LOOM.

SPECIFICATION forming part of Letters Patent No. 621,138, dated March14, 1899.

Application filed October 20, 1898. Serial No. 694,096. (No model.)

T0 all whom, it may concer/1,:

Beit known that I, EUGENE RENZ, a citizen of the United States,residingat Stirling, in the county of Morris and State ot' New Jersey, haveinvented certain new and useful Improvements in Looms, of which thefollowing is a specification.

My invention relates to looms, and vmore particularly to the lay orbeating-up mechanism and the dwell-stand intermediate the lay-sword andthe crank-shaft connector.

In the class of looms to which my improvements are to be applied thedwell-stand, as it is termed, is rigidly attached at its lower end tothe lay-sword and pivotally attached at its upper end to thecrank-connector and the lay-sword. When the lay protects to stop theloom, the crank-shaft does not stop immediately, but pushes by means ofthe crankconnector upon the dwell-stand in an upward direction, and thedwell-stand being rigidly attached to the lay-sword at its lower endcannot yield, and consequently the dwellstand is often broken andsometimes even the lay-sword.

The object of my invention is to provide relief for the lower end of thedwell-stand, so that the upper end of the stand may swing or move on thepivot-pin connecting it with the lay-sword when the lay protects, andthus prevent the breaking of the dwell-stand or of the lay-sword.

My invention consists in certain novel features of construction of thedwell-stand, and more particularly in providing for the yielding ormoving of the lower end of the dwellstand, so that the upper end mayswing or move on its pivot connection with the lay= sword when the layprotects.

Referring to the drawing, I have shown in the drawing a sectionalelevation of portions of a loom of well-known construction and operationwith my improvements applied thereto.

In the accompanying drawing, 1 is the loom side or end. 2 is thecrank-shaft; 3,the crank connector, and 4 the crank-connector pin,connecting the crank-connector 3 with the rear upper end of thedwell-stand 5. The front upper end of the dwell-stand 5 is pivotallyconnected with the rear of the lay-sword 7 by the pin 6. The lay-sword 7carries the lay S, on which is the race-plate 9, and the lay-foot 10 ismounted on the rock-shaft 11.

The protector-rod stand 12 is secured to the lay 8 and carries theprotector-finger 13,which 55 is adapted to engage the bunter-lever 14 onthe bunter-stand 15, secured to the breast-beam 16 when the layprotects.

All of the above parts are of the ordinary construction and operation inthe class of 6o looms to which my improvements may be applied.

In the ordinary construction of the dwellstand 5 the lower end 5 is madea part of or rigidly secured to the lay-sword 7. In my improvedconstruction the lower end 5 of the dwell-stand 5 is not rigidly securedto the lay-sword, but is connected therewith so as to have a movementindependent of the laysword to allow the upper forward end of the 7odwell-stand 5 to swing or move on its pivotpin 6 when the lay protects.In thisinstance I have yieldingly connected the lower end 5 of thedwell-stand 5 of the lay-sword 7 by means of a pin 17, which extendsloosely through a hole in the lower end 5 of the dwellstand 5 andthrough a hole in the lay-sword and is secured to the lay-sword by asetscrew 18.

A washer 19 is loosely mounted on the pin 8o 17 and bears against theinner surface'of the vopening in the lower end 5' of the dwell-stand 5.A spiral compression-spring 2O encircles the pin 17 intermediate Athewasher 19 and the head of the pin 17.

The spring 2O acts to hold the lower end 5' of the dwell-stand 5 againstthe lay-sword 7 to move with said lay-sword, but also allows the lowerend 5 of the dwell-stand 5 to yield and move away from the lay-sword, sothat 9o the upper front end of the dwell-stand 5 can swing or move onits pivot-pin 6.

The operation of my improvements will be readily understood by thoseskilled in the art.

When the lay protects, the protector-finger 13 strikes the bunter-lever14, which falls back against the stand 15 in the ordinary way. Themovement of the bunter-lever 1'4, acting through a mechanism of ordinaryconstruction and operation, (not shown,) throws reo oi the power; butthe crank-shaft 2 does not stop immediately, but pushesby means of thecrank-connector 3 upon the dwell-stand 5 in an upward direction, whichcauses the upper end of said dwell-stand to swing` or move on thepivot-pin 6 and the lower end 5 of said dwell-stand to move away fromthe lay-sword and compress the spring 20, thus relieving the sword anddwell-stand from the strain which might break the sword or dwellstand.

The advantages of my improvements will be readily appreciated by thoseskilled in the art.

It will be understood that I do not limit myself to the particularmechanism shown in the drawing for yieldingly connecting the lower endof the dwell-stand with the laysword, as other equivalent means may beused EUGENE RENZ.
